Fluorescent mhlophe agentyiarhente esetyenziswa ngokuqhelekileyo mhlophe kwiiplastiki ezininzi, ukutyabeka, kunye nabavelisi bephepha, abaneempawu zedosi encinci kunye nesiphumo esicacileyo sokwenza mhlophe.Ngokukodwa kwizandla zabavelisi bezinto ezihlaziyiweyo, kuye kwaba liyeza elilungileyo lokuvuselela iimveliso.
IjikisiweIplastiki yePVCIthambekele kwi-oxidation ye-thermal ngexesha lokucutshungulwa, okukhokelela ekubeni imveliso ijike ibe mnyama kwaye ityheli, okanye ibe tyheli ngenxa yokuvezwa ixesha elide ekukhanyeni kwe-ultraviolet kunye nokuphendula kwe-oxidation yendalo, zonke ezi ziziganeko eziqhelekileyo.Abanye abavelisi baya kukhetha ukusebenzisa i-titanium dioxide ukwenza mhlophe, kodwa emva kokongeza inani elikhulu le-titanium dioxide, ayinakwenziwa ibe ngumhlophe ofanelekileyo, kodwa iya kubangela ukuba umgangatho weplastiki wehle ngenxa yokongezwa okugqithisileyo.
Umsebenzi we-agent emhlophe ye-fluorescent kukuphucula ubumhlophe beplastiki ye-PVC, inqanda ukutyheli, kunye nokuphucula isimo sezulu kunye nokukwazi ukuguga kweemveliso.Yeyokuba mhlophe kwamehlo okubonakalayo, ngoko ke ukongeza iiarhente ezimhlophe ze-fluorescent kwiimveliso ezahlukeneyo zeplastiki aziyi kutshintsha iipropathi zemveliso ngokwayo.
Emva kokuba i-agent emhlophe ye-fluorescent ifakwe kwi-PVC yeplastiki, inokuthatha ngokufanelekileyo ukukhanya kwe-ultraviolet ekukhanyeni kwendalo, iguqule ibe yi-blue violet ukukhanya kwaye ibonakalise, ukuze kufezekiswe umphumo wokuba phuzi kunye nomhlophe.Esi siphumo asikwazi ukufezekiswa nge-titanium dioxide kuphela.
Ngokomgaqo wokusetyenziswa kwee-agent ezimhlophe, siyakwazi ukuba iimveliso zeplastiki zithatha inxalenye yokukhanya kwe-ultraviolet emva kokongeza i-fluorescent whitening agents.Njengoko imveliso inciphisa ukuhlaselwa kokukhanya kwe-ultraviolet, ukuchasana kwemozulu ngokwemvelo kuphucula kakhulu, ukwandisa ubomi bayo benkonzo.
